Halogenated compounds are particularly easy to identify by their mass spectra because chlorine and bromine occur naturally as mixtures of two abundant isotopes. chlorine occurs as 35cl (75.8%) and 37cl (24.2%); bromine occurs as 79br (50.7%) and 81br (49.3%). for the compound chlorocyclohexane, c6h11cl: at what masses do the molecular ions occur? (list in order of increasing mass separated by commas, e. g. 120,122.) what are the percentages of each molecular ion?

The increasing order of masses of molecule ions:

118 g/mol(75.8%) ,  120 g/mol(24.2%)

Explanation:

Chlorine occurs as 35-Cl (75.8%) and 37-Cl (24.2%).

Atomic mass of 35-Cl = 35 g/mol

Atomic mass of 37-Cl = 37 g/mol

Mass of Chlorocyclohexane in which 35-cl is present as a chlorine atom:

Mass of Chlorocyclohexane in which 37-Cl is present as a chlorine atom:

The increasing order of masses of molecule ions:

118 g/mol(75.8%) < 120 g/mol(24.2%)

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
